Why We Like The Yeti SB120 T4 XX Eagle T-Type Carbon Wheel Mountain Bike

From cross-country rides to trails that require a bit more capability, the Yeti SB120 is our go-to choice when we need a bike that is fast, agile, and still down to get a little rowdy. The SB120 is a short-travel, 29-inch wheel mountain bike with aggressive geometry and an efficient suspension system, allowing it to handle more than its travel numbers suggest. The SB120 features a 66.5-degree headtube angle for the perfect middle line of being capable on the descents while still maintaining precise handling. Size-specific seat tube angles and six frame sizes give us a perfectly balanced ride no matter our size frame. Yeti's patented Wishbone suspension link was revised this year solely for the SB120, giving it a more compact, one-piece design that allows for more downtube clearance, a more linear progression curve, more room inside the front triangle for water bottles, and a lower stand over height. The SB120's progression curve was revised to give it a more linear 11-percent progression curve and a high leverage ratio, allowing for greater small bump sensitivity and a more supportive mid-stroke that helps to increase its bottom-out resistance.

The T4 XX Transmission AXS Carbon Wheel build of the Yeti SB120 is a top-level build with the absolute best components to complement this superbike. Yeti's TURQ carbon frame uses premium carbon fiber to give us the stiffest and lightest frame possible. SRAM's XX Transmission AXS drivetrain is SRAM's top-level drivetrain in their newly-released Transmission series. It offers flawless electronic shifting, a durable design, a hanger-less interface, and an overload clutch that can move out of the way to absorb impacts to protect the derailleur. DT Swiss EXC 1501 carbon wheels help save weight, add stiffness, and are paired with DT Swiss's premium 240 hub that features a Ratchet EXP 36-tooth engagement. SRAM's G2 Ultimate are the lightest 4-piston brakes SRAM has ever made and offer tons of stopping power and a contact adjustment wheel at the levers for the perfect bite. Fox Factory 34 FIT4, 130mm fork, has tons of rebound and compression adjustments to get our ride perfectly tuned to our riding style. The Factory DPS shock is capable, lightweight, and has many adjustments and a climb switch for efficiency.

*Due to a high demand in the global supply chain and bike industry since the start of the pandemic, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be of equal or better spec level.
